WINDMILL.

SPECIFICATION forming part of Letters Patent No. 657,420, datedSeptember 4, 1900.

Application filed December 26, 1899- Serial No. 741,705. (No model.)

pensive one in which the fans or blades will be protected or shieldedfrom the force of the wind as they come into the same, whereby a maximumpower is obtained from a given force of wind.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and point-ed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a windmillconstructed in accordance with this invention. Fig. 2 isa similar view,one of the vertical wind-wheels being re moved. Fig. 3 is a detail viewillustrating the construction of the pitman for connecting the crank ofthe Wind-wheel shaft with the pump-rod.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a tower, which may be constructed of any suitable materialand upon which is mounted a support consisting of an upper tubularbearing-sleeve 2 and a series of inclined supporting rods 3, secured attheir lower ends to the tower and connected at their upper ends to theouter bearingsleeve 2, which is stationary and which is adapted toreceive a rotary bearing 4, consisting of an inner tube or sleeve5 andapair of diverging arms 6, extending upward from the sleeve 5. The innerbearing-sleeve 5 is provided with a horizontal siipporting flange 7,resting upon the upper edges of the outer stationary bearing-sleeve, andthe diverging arms, which extend upward from the inner rotarybearing-sleeve, are provided at their upper ends with bearings for thereception of a horizontal wind-Wheel shaft 8, having a central crank 9and carrying a pair of opposite vertical wind-wheels 10. The crank ofthe wind-wheel shaft is connected with the upper end of a pitman 11,which is provided at its lower end. with a ball 12, arranged in asuitable socket 13 of a pump-rod 14. The wind-wheels by being located atopposite sides of the crank'of the wind-wheel shaft of the tower andbeing adapted to counterbalance each other. The rotary frame is providedwith a lower bearing-ring l8, and it has central standards 19 risingtherefrom and arranged in pairs at opposite sides thereof. The u pper ends of the standards are secured to horizontal top bars 20, arranged atopposite sides of the wind-wheel and connected at their front and rearends by inclined braces, the front inclined braces 21 being arrangedopposite each other, as clearly shown in Fig. 2, and the rear inclinedbraces 22 and 23 being arranged at diiferentinclinations, as hereinafterexplained. The horizontal top bars have their rear ends converged andsupporting the inner end of the vane, being secured to the same at thelower end thereof. The vane is supported at its upper edge byoppositely-disposed converged diagonal braces 24. The rear brace 22extends to the lower edge of the vane and the other rear brace 22extends to the top of the same. The braces 24 are further supported by avertical rod 25.

The wind-wheels are composed of blades secured to suitable hubs, whichare fastened to the shaft, and the shield 16, which is arranged inadvance of the lower portions of the wheels, is secured at its top tothe upper ends of the front braces 21 and the front ends of the top bars20. The lower ends of the converging braces 24 are secured to the shieldat points between the ends thereof, and the bottom of the shield isattached to the rotary frame adjacent to the lower bearingring. The topbars of the rotary frame are secured to the diverging arms of the rotarybearing. The wind-wheels are located at opposite sides of the rotaryframe, as clearly shown in Fig. l, and the curved shield is adapted to 1cover the blades of the windrwheels. as they 7 na-led onthedi vergi'ngarms, a rotary frame supported by'the tower and connected with 1 thesaidarms, a; shield arranged at 0110261111 L of the frame, and a vanearranged? at the other end of the frame and adapted to coun- I comeintothezwin'd, and the? latter; d'ibGSfinOt operate onv the'low'erportions of the'windwheels and check the rotation of thesame.

It will be seen that the windmill is simple and comparativelyinexpensive in construe.- tion that it is strong and durable; and thatthewind-wheels balance each other and the shield is balanced by thevane. It will also be parent that the shield is firmly supported by therotary frame and that it is adapted to exelude the wind from.t-h'elower. portionsofi the.v

wind-wheels, and thereby prevent the same from being retardedby-theaction-ofthe wind on the blades as the latter come into the wind.WhatIclaim is- 1. windmill comprising towel, a: snipport consistin g-ofanouter bearin-gesleea 'e, an'd supporting-rods; av rotary bearing:provided withdivergingf arm-s and"v having an in nenroi tary sleevefitting within the-said sleeve and. supportedby the same, ahorizontaishaft jour terbalanpe the-iishield substantially as dese'nioedi Q f a.
